+%
+% VERSION HISTORY:
+% 1.0 8/93
+% 1.2 10/93 major rewriting, only basic mode still
+% compatible with 1.0;
+% support for raw text list added
+% 1.3 fixed a minor bug of 1.2;
+% support for commenting out letters added
+% 2.0 11/93 compatible with 1.2, 1.3;
+% labels utility added; support for fixed number
+% of parameter lines added
+% 2.03 2/94 TAB char represents 8 spaces instead of 4;
+% fixed a bug on multi-columns output
+% 2.1 1/95 added parameter checker and dynamic array facilities;
+% compatible with LaTeX2e;
+% slight name changes: \figbox -->\textbox
+% 2.2 1/95 renamed an internal command (\array) to avoid
+% conflict with LaTex.
+% 2.3 5/2003 separated programmer's manual from the style file,
+% added a new user manual.
+%
+%
